Find where they are. Teach from there.

The Origin Story

I was sitting across from a Year 9 student who couldn't solve a basic algebra problem. She was bright, engaged, trying hard. But something wasn't clicking.

So I went backwards. I gave her a multiplication question. She couldn't do it.

Not because she wasn't capable. Because somewhere around Year 5, a foundational concept hadn't been secured. And every year after that, the curriculum kept building on top of something that wasn't there.

I saw this over and over. For twenty-five years, across more than 20,000 students, Prep to Year 12, in both English and Maths. The same pattern: students weren't struggling because the content was too hard. They were struggling because a foundation from years earlier had never been found.

A Year 6 student who could see that fractions didn't make sense, but couldn't explain why. A classroom of twenty-five Year 7 students whose actual readiness spanned from Year 3 to Year 8.

Year levels describe age. They don't describe readiness.

The Misconception Atlas

Over two decades of rebuilding curriculum from scratch, my team and I catalogued over 1,881 recurring mathematical misconceptions across the Australian Curriculum.

Every mathematical concept has prerequisites. When a prerequisite is broken, everything built on top is unstable. Most of the time, the break happened years ago and no one found it.

This body of work became the Misconception Atlas: a living map of where understanding breaks down and what needs to come first.

The Atlas underpins every Spectrum booklet. It's why the content is sequenced the way it is, why each term builds on the one before, and why a student using these booklets is never asked to learn something they're not yet ready for.

The CSIRO Partnership

We're working with the CSIRO to build a dynamic model of the Misconception Atlas. This partnership brings scientific rigour to what twenty-five years of classroom teaching revealed: that learning has a structure, and when you respect that structure, students thrive.

About Thuy Pham

Founder, Spectrum Tuition and Spectrum Books

I started Spectrum Tuition from a single classroom. It grew to fifteen campuses across Melbourne. Along the way, I taught more than 20,000 students and learned something that changed everything I thought I knew about teaching: the problem is almost never where it looks like it is.

The work of cataloguing misconceptions across the Australian Curriculum became the Misconception Atlas, now being developed further with the CSIRO. Spectrum Books is the classroom-ready version of everything those twenty-five years taught me.

I still get excited when a teacher tells me they found the exact moment a student's understanding broke. Because that's the moment everything turns around.
